I have a 1999 Explorer with 4.0 V6 OHV engine. What is involved with replacing the lower intake manifold gasket? I recently replaced the upper so I have the lower gasket and think the lower is leaking. There is no oil or coolant loss problem but I get 0174 code and think I saw some leaking when using Seafoam thru the vacuum lines today. I will repeat the test before doing anything.
